Solution

I think I found the issue.

Apple has changed the rt.jar to classes.jar which is located in.

/System/Library/Frameworks/JavaVM.framework/Versions/<your_java_version>/Classes/classes.jar

I need to modify my pom.xml to show it the path to classes.jar.

Edit : In a multi-mudule project. Creating soft links to classes jar in the lib directory is much better.

sudo ln -s ../../Classes/classes.jar ./rt.jar

Well sudo because writing in the result of /usr/libexec/java_homecommand ,which is your java home directory, requires administrator priviligies.
